UNITED STATES PATENT EEICEe9 JAMES M. HADDEN, OF POGHKEEPSIE, NEW YORKA GASAAPPARATUS.

SPECIFICATION forming part of Letters Patent N0. 628,000, dated July 4, 1899.

Application filed September 30, 1898. Serial No. 692,319. (No model.)

To all whom it may concern:

Be it known that I, JAMES M. HADDEN, a citizen of the United States`,residing at Poughkeepsie, in the'county of Dutchess and State of New York, have invented new an`d useful Improvements in Gas Apparat-us, of which the following is a specification.

My invention relates to improvements in illuminating-gas apparatus, and more particularly to the superheater of the Lowe or other standard type of gas apparatus; and the object is to improve the construction and increase the ef ciency of the apparatus by collecting the waste gases and other heated products of combustion, which heretofore have been allowed toescape from the superheater into the atmosphere, and conducting them to the fuel-economizer, which will utilize the heat for steam-making purposes.

With this object in view the invention con# sists in the construction, combination, and arrangement of the apparatus, as will be hereinafter more fully described, and particularly pointed out in the claims.

The figure in the drawing is a diagrammatic view of the upper end of a gas-superheater and the connections embodying my invention.

1 denotes the superheater, provided at itsV upper end with a central opening 2, which is closed by a valve 3, carried by the parallel arms 4 4, xed on the shaft 5, journaled in the brackets 6 6, secured to the upper end of the superheater. One end of the shaft 5 terminates in a crank-arm 7, from which a connecting-rod 3 extends to a hand-lever 9, fulcrumed to the external face of the wall of the superheater. The opposite end of the shaft 5 also terminates in a crank-arm 10, from which a rod 12 extends to the projecting arm of the. damper 13, fulcrumed in thecasing 14, forming a part of the horizontal flue 15, leading from the hood 16, supported by the standards 17 17 above the superheater. Theupper end of the hood communicates with the stack 18.

19 represents an annular horizontal shoulder or collar fixed in the hood to form a seat for the damper 20, fixed on the rock-shaft 2l, and one end of this shaft terminates in a vertical arm 22, provided with a pendulating weight, as shown."

From the arm 22 a chain or rope 23 extends Weight carries the arm beyond the center and over to the position shown in the dotted lines, with the vdamper resting against and closing the end of the flue 15, so that communication with the flue is cut off and at the same time communication is established between the hood and the stack.

Heretofore the large volume of heated gases which escaped from the superheater when the valve 3 was opened was lost by passing through the hood and stack into the atmosphere,where as in the present instance the damper 2 0 being closed when the valve 3 is raised the damper 13 is opened, which permits the gases arising from the superheater to pass from the hood through the flue 15, whence they are conducted to the f uel-economizer, (not shown,) so as to utilize the heat for steam-making purposes.

Although I have specicall y described the construction and relative arrangement of the several elements of my invention, I do not desire to be confined to the same, as such changes or modifications may be made as clearly fall Within the scope of my invention without departing from the spirit thereof.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, 1s-

1. In combination, the superheater, the hood, the stack and an independent flue communicating with said hood, a damper located in the hood and adapted to alternately cutoff communication between the hood and stack or iiue, an independent damper located in the flue, a valve on the superheater, and means for simultaneously operating said valve and flue-damper, as and for the purpose set forth.

2. The combination with the superheater and its valve, of the hood, its stack and the horizontal flue, of a damper located in said ICO flue and operatively connected to said valve, as and for the purpose set forth.

3. In a gas-making apparatus, the superheater 1, the valve 3 and shaft 5 provided with the crank-arm 10, the hood 1G, the damper 2O mounted in said hood, the stack 18 and horizontal flue 15, communicating with said hood, the damper 13 mounted in said flue and the rod 12 connecting said damper 13 and crank-arm 10, substantially as shown and described.

4. In a gas-making apparatus, the combination with the superheater, of a valve corn-4 municating with said superheater, a hood mounted above said valve and provided With JAMES M. HADDEN.
